On a first side, facing the user in an in-use position, the cover displays a liquid pervious first cover-sheet (3) and on a second side, facing away from the user in an in-use position, the cover displays a second cover-sheet (4). On said first side is provided longitudinal liquid barrier means (17, 18) folded into tunnel shape, forming a channel (17', 18') with a longitudinal tunnel wall (17", 18").
